PHLEGM v7 networking listing update

- WET/REMOTE networking derives the online catalog base from the master records.
- Canonical form: https://gamepadenforcer.com/<$proper>/?prj=<$project>&v=<$version>
- PHLEGM v7 resolves to: https://gamepadenforcer.com/phlegmulator/?prj=PHLEGM&v=7
- Catalog/listing links remain authoritative; PHLEGM does not synthesize download=<category>&id=<id> URLs.
- Existing manifest and per-machine requests append their parameters with '&' to the versioned base query.
- Definition bundle acceptance is scoped to the derived versioned catalog base.
